I feel that that level of spending control has gone too far towards the loyalty schemes. Once you remove the idea of earning points from a decision then you are much more likely to choose an alternate solution. For instance
Red Energy was giving me points per year but those 2,000 'free' points were costing me $200. I changed provider.
Giving up on QFF (and losing Gold) means my work flights to Asia have been with other carriers $500-$600 cheaper per itinerary.
Who is really in charge of the spending decisions? It's Qantas or Virgin or BP that they can send an email and people jump to change their spending to the new direction. That's the value of the frequent flyer programs.
I did some numbers on this recent BP promotion
Let's say it's me driving a modest but economical SUV driving 25,000 kms per year at 7 litres per 100kms.
I will need 1,750 litres of fuel each year at say $1.75 per litre = $3,000 / annum
So, as a consumer, if I exclusively buy BP fuel for the next 8 years I MIGHT be able to find a redemption ticket and still pay $110 in taxes.
ORRRRRR
Given that BP is usually more expensive in my area, let's say I just saved $0.2 per litre instead saving $350 per year and compared flight prices. I can actually fly once per year just for NOT buying BP.
For me personally I have started ignoring both Velocity and Qantas promotion point offers and just enjoy the cost savings from outside those schemes.
